Used Hyundai i30 Catalytic Converter

The i30 is a petrol and diesel front-wheel-drive hatchback, and all of its engine variants do carry a catalytic converter as part of the exhaust emissions system. Petrol engines have a traditional cat, while diesel engines combine the cat function within a more complex system that also includes a diesel particulate filter (DPF) on Euro 5 and Euro 6 compliant models. So the part does exist across the range, but the exact unit fitted depends heavily on engine code, fuel type, and the emissions standard the car was built to.

The i30 moved from the first generation (Mk1, 2007–2012) to the second generation (Mk2, 2012–2017) with significant changes to engine choices, exhaust routing, and emissions compliance, moving from Euro 4 territory into Euro 5. These are different platforms with different exhaust systems, so a cat from the Mk1 era is very unlikely to be a straight swap onto a Mk2. Confirm with the breaker against your exact registration and engine code before ordering.

Trim level does not affect which catalytic converter is fitted to your i30 – the cat is determined by engine code, fuel type, and the emissions era of the vehicle, not whether the car is an S, SE, Premium, or any other specification. You may find cosmetic differences between cars of different trims, but under the bonnet and along the exhaust the cat will be the same across trims sharing the same engine. Focus your search on matching engine code and fuel type rather than trim name.

The Mk2 i30 received a facelift in 2015, which brought some styling and feature updates but did not introduce wholesale engine changes. However, whether the cat is interchangeable between a pre-facelift and post-facelift Mk2 depends on the specific engine code and any emissions specification differences between the two build dates. This is strong confirm-with-the-breaker territory – give the breaker both registration numbers so they can check the exact part references before supplying.

Yes, diesel i30s built to Euro 5 and Euro 6 standards carry both a catalytic converter and a diesel particulate filter (DPF), and on some engines these may be housed in a combined unit rather than separately. If you need the cat specifically, make sure you and the breaker are both clear on whether you need the cat alone, the DPF alone, or a combined cat-DPF assembly, as supplying the wrong unit is a common mix-up. Confirm exactly what your vehicle has by sharing your registration with the breaker so they can match the correct part.

Different engine displacements on the i30 have different engine codes and different exhaust configurations, so a cat from a 1.4-litre variant is not a reliable match for a 1.6-litre variant even within the same generation. Beyond physical fitment, using a cat from a different engine could cause issues with emissions readings at MOT. Always match the replacement cat to your specific engine code rather than just the body shape or model year, and confirm with the breaker before purchasing.
